Abstract

A personal media viewing device has a frame that adjustably holds a pair of lenses. The frame has tracks along a bottom inside portion that guides the lenses as a lens adjustment knob is turned. The adjustment knob is attached to a translating screw shaft that has opposingly threaded portions that interact with a left and right traveling nut attached to each lens and moves each lens in an opposite direction. An elastic strap is used to removably hold a personal media device to the frame and a head attachment portion is provided to allow a user to operate the personal media viewing device hands free. The adjustment knob allows a user to adjust the lenses to an off-axis position selected to reduce eyestrain, headaches and other non-desirable effects associated with viewing a device in front of the user'"'"'s eyes.
